Fully funded might be a matter of perception. There are a bunch of things that I know of (working mainly with one branch) that were available for them, but they weren't able to afford it.

Shoot, one of the guys I work with (former F-16 pilot) tells horror stories of losing flight time because his squadron didn't have the money to replace canopies when they needed to (the canopies are prone to abrasion and need to be replaced occasionally). The Army could have had fully integrated Level 4 UAV control in the cockpit of their attack helicopters ages ago but didn't have the money (it was first demonstrated in 1998 or 1999). Special Operators (SEALs, Special Forces, Marine Recon, etc) often buy their own equipment because their units can't afford the stuff they need (which is specialized and different from the rest of the unit).

Ugh, I could go on forever about this topic
